There is a great book called the Spice Bible. You will love it. It gives you spice blend recipes from all over the world. Some exotic blends can cost you up to $14.50 for 4 ounces when you can make it your self for $4.50 a pound. Also there is a great site I go to, to buy spices wholesale. You can get a pound of mustard seeds for $2.50 a pound. It is called the AtlanticSpicecompany.com. No frills but cheap prices and very fresh.
